I have laptop mode enabled on my system though

Laptop mode magically started working without me changing anything, so I guess the above steps are sufficient. I must have not rebooted enough times (or I maybe just did a log off - log on and that isn't enough).

Thanks for the tips about configuring laptop-mode. I also picked those settings in laptop-mode.conf. Just take care to have the LAPTOP_MODE_ENABLED=true inside /etc/deffault/acpi-support so that you don't have to turn it on manually every time - it seems this does work in the end.

please what line is this setting on inside the acpi-support file?

1

I appended it to the end of the file, because it didn't exist in my acpi-support file. Take a look at the original question, I edited it to be more clear.

Thanks for the tip, though I think echoing to /proc is a temporary solution - one would have to repeat it after every system boot. See my comment to the original question, I got the acpi config file method working after all.

nope. when you do it as root, it sets it permanently.

OK, well then this is another method of doing it.
